高能α粒子与原子核的散射

α-Nucleus Scattering at High Energies

本文以“两个复合粒子系统的高能散射理论”为骨架,计算了1.37 GeV的α粒子与^(12)C和Ca的同位素的弹性和非弹性微分截面。计算结果与实验值符合得比较好。发现在弹性散射中虚激发的贡献是重要的。

In this paper, the differential cross sections of the elastic and inelastic scattering of alpha-particle of energy 1.37 GeV on the 2^+ and 3^- excited states of ^(12)C and Ca isotopes are calculated by the method of the inelastic two-composite-particle system scattering theory at high energy. The results are in agreement with experimental data. The importance of the virtual excitation in calculating the differential cross section of the elastic is discussed.
